We present a variant of the protocol stack for anonymous authentication
implemented in German personal identity documents. We strengthen the system by eliminating
group keys - a potential target of attack for an powerful adversary aiming to undermine
Restricted Identification mechanisms in this system.
We provide a mechanism of authentication that merges Chip Authentication protocol with
Restricted Identification.
